head to head
Neither is meaningfully harder - they pose close to the same test. The widest gap is variance, and it is a single point.

Optimization · Pure Optimization
Calm path-routing logic puzzles that are pure constraint satisfaction.

Optimization · Pure Optimization
Serene puzzler where rewinding time untangles dioramas of childhood memories.
Lyne leans Optimization (Pure Optimization); The Gardens Between leans Optimization (Pure Optimization).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Lyne
Tracing paths has no time pressure
The Gardens Between
Only scrubbing time forward and back
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Lyne
Pure solo logic - no opponent
The Gardens Between
No opposition exists
The Gardens Between leans a little harder on variance, though the gap is small.
Lyne
Every board is fully visible and deterministic
The Gardens Between
Deterministic dioramas
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Lyne
Each board is a solvable path-routing constraint puzzle
The Gardens Between
Each island is a clean time-manipulation logic puzzle
A matching score does not mean a matching test. Two games can both sit at 10 on execution and demand completely different things of you - which is why the reasoning above matters more than the number beside it.
